FIELD

The subject matter herein generally relates to a paper clamping mechanism and an automatic page-turning and UV(ultraviolet)-scanning system having the same.

BACKGROUND

A scanning device is usually connected to a computer, and configured to capture images and convert a graphic or image into a digital signal using a photoelectric technology and a digital processing technique.
